Top 5 Amazing Science Experiments You Can Do At Home
5 - A Magnetic Liquid
Ferro Fluid is a liquid that contains magnetic nano particles within it, and becomes strongly magnetized in the presence of a magnetic field. It was invented in 1965 by NASA's Steve Papell as a liquid rocket fuel that could be drawn toward a pump in a weightless environment like space by applying a magnetic force on it. You can easily buy some of it in a bottle online and you can have fun anywhere as long as you have a magnet laying around nearby. The closer the magnet to the bottle the more it changes shape. You can play with the magnetic liquid as much as you like.
4 - Instant Freezing Water
This experiment is really easy for anyone because all you need is a bottle of purified water and a freezer. Just stick the bottled water into the freezer and wait a few minutes so the water can get bellow its freezing point. It's still a liquid when you take it out, but the second you twist the cap it turns into a slush. You can also just twist the cap carefully and pour it onto an ice cube to create an ice tower. It's a simple experiment, but is really fun to do. Plus you can surprise family and friends with this instant freezing water trick and they'll be left wondering how you did it.
3 - Waterproof Sand
Magic sand is made from sand coated with a Hydrophobic element which repels water. The Hydrophobic element causes the sand to form cylinders which minimizes surface tension when exposed to water causing it to sink. When the sand is inside the water it holds it's shape and can be molded into structures under water unlike regular sand that remains free flowing and can't keep it's structure. When the sand is taken out of the water it is completely dry and free flowing. The sand is fun to play with in the water and might be useful at the beach so you don't have to worry about the water ruining your sand castle.
2 - Amazing Oobleck
Oobleck is a Newtonian fluid which means it has properties of both a solid and a liquid. The name oobleck comes from the Dr. Seuss book, “Bartholomew and the Oobleck.” In the story, oobleck, a gooey green substance, fell from the sky and wreaked havoc in the kingdom. When left alone oobleck remains in its liquid form, but when you try applying force to it it turns into a solid. You can punch and squeeze it as much as you like and it will remain a solid, but when let it stay in your hands it will return back to its liquid form and drip right between your fingers. Oobleck is really fun to mess around with since the properties are so cool. Not to mention it's really easy to make!
1 - Potato Battery
Here's another fairly easy experiment. All you need is 2 potatoes, 2 short heavy copper wires, 2 nails, 3 alligator clips, and an LED light. A tutorial on how to put everything together is down below. After you finish putting everything together and your connect the wires to the LED light, you should see a small light in the LED. The potato is actually generating electricity and has enough to power the LED. You can try this experiment with any fruit or vegetable and you should get the same result if you did everything correctly.
